Does anyone know the difference between freeze dried powder Semaglutide and the Brand Name Pharmacy Ingredients pen. The only thing I found out was one type is the ingredient that is in salt form or salt based, and the Brand name Pen is just semaglutide. Could this be the company trying to say it is not exactly like the pen so be careful because there is some difference but if they say it is bad or negative then one might think if there is a small difference then both types can be a problem? Is the powder and pen act the same exact way?
